Medicinal

The seed oil is sometimes used as a cathartic, although it may cause strong irritation and even poisoning. The oil is applied both internally and externally as an abortifacient[].

Seeds are used fresh as a purgative and emetic[, ]. A very powerful purgative, their use has been almost abandoned in traditional medicine in Mexico, although they are officinal in the Mexican Pharmacopoeia[].

The latex is used externally in the treatment of infected wounds, ulcers, skin infections and scabies. In Indonesia one of its local names is 'yodium' ('iodine'), which reflects the popular use as a wound-healing remedy[].

In Indo-China, dried roots are given as a decoction against indigestion and colic; they are also prescribed as a tonic to treat orchitis and oedemas[, ].

The leaves contain saponins[]. They are used as a purgative, and in the treatment of dysentery and scabies[].
